Minimoto oil seals 15x24x5 racing Polini

PERFECT TAKE Polini has created a series of sealing rings (oil seal) for the most common models of mopeds and scooters in circulation. Perfectly interchangeable with the originals, they can be mounted both on the crankshaft and on the primary shafts of the CVT transmissions. Made of FKM (fluorocarbon rubber) to withstand the highest thermal stress, they have the sealing lip coated with PTFE (polytetrafluoroethylene); this feature, in addition to making them more durable than standard sealing rings, means that they have a significantly lower coefficient of friction thus ensuring less dispersion due to friction and at the same time maintaining lower temperatures. These sealing rings have been designed for racing engines but are also perfectly suited to standard engines without an upgrade kit where, due to the low power available, the reduction in friction makes it possible to achieve higher revs. TECHNICAL CHARACTERISTICS Body in FKM. Steel metal armor. Inner lip coated in PTFE with very low friction coefficient
